BRICK-HANDLING APPLIANCE.

Specification of Letters Patent.

Application filed July 2, 1909.

Patented Jan. 25, 1910.

Serial No. 505,750.

My invention has to do with the replacing of old brick at the bottoms of coke ovens with new brick; and it contemplates the provision of a device through the medium of which a workman standing outside a hot coke oven may expeditiously and easily take out old brick and as readily place new brick in proper positions at the bottom of the oven and in that way avoid the delay of waiting for the oven to cool.

The invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming a part of this specification, in which:

Figure l is a side elevation, partly broken away, of the device constituting the best practical embodiment of my invention of which I am cognizant, as the same appears when its grippers are in their innermost positions. Fig. 2 is an inverted plan view of the device with the grippers in their outermost positions. Fig. 3 is a front elevation with the working parts positioned in the same manner as in Fig. 1. Fig. 4 is a detail vertical section, taken in the plane indicated by the line 44: of Fig. 1. Fig. 5 is a detail transverse section taken in the plane indicated by the line 5-5 of Fig. 2. Fig. 6 is a detail longitudinal vertical section illustrative of the connection intermediate the forward end of the longitudinally movable rod and the plunger or vertically movable rod of the device.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which:

A is the body of my novel device which is hollow and preferably in the form of a tube, as shown. The said body is provided at an intermediate point of its length with a support B which comprises a ring a, a set screw Z) for adjustably fixing the support at the desired point in the length of the body A, a yoke c fixed to and depending from the ring a, and wheels (Z carried by the yoke. Obviously when supported by the means just described, the device is adapted to be expeditiously and easily moved, and it will also be manifest that the body A and the support frame may be rocked in the wheels (1 when it is desired to lower or raise the grippers at the forward end of the device.

Fixed to the rear end of the body A is a loop-shaped handle 6 having its rear bar 7 shaped to form a keeper, and journaled in and extending throughout the length of the body A and beyond the rear and forward ends thereof is a tubular shaft C having at its rear end a handle g and at its forward end a sector gear h. It will also be seen by reference to Fig. 1 that an endwise movable rod D extends loosely through the tubular shaft C, and that hinged and adapted to swing vertically on the rear end of the said rod is a supplemental handle 2' having beveled teeth 7' and adapted, therefor, to be adjustably fixed on the keeper portion 7 of the main handle 0.

Fixed on and extending above and below the forward end of the body A and in advance of said body is an upright frame E, and extending loosely through the top and the bottom of said frame is a vertically movable plunger F. This plunger is preferably made up of an upper pin is, and an open portion Z, loosely connected to the lower end of the pin 1'; and extending downwardly about the proportional distance illustrated and terminating in a depending shaft portion at which extends through and below the bottom of the frame E and has a rotary head a loosely mounted on its lower end for a purpose hereinafter set forth.

Journaled in the bottom of the frame E and surrounding and adapted to turn about the portion m of the plunger F is a sleeve G, having a miter gear p at its upper end, intermeshedwith the before-mentioned sector gear h. At its lower end the sleeve G is fixed to arms H which depend and diverge therefrom, and fixed in turn to the said arms H is a rectangular, horizontally disposed frame .l, each bar of which is provided with a pair of depending lugs 1, and is also provided with a depending bifurcated lug s, the latter being arranged at the inner edge of the bar and about midway between the lugs 1 Connected in a hinged manner through pintles t with the lugs r of frame are a plurality of swinging grippers J having 1nwardly directed and serrated lower edges '10,

are

and by reason'of' the construction described it will be manifest that the workman standing at the outer end of'the body-A isenablled c] ose the grippers J without interfering with the described turning of the several grippers about a center, I provide in addition to the vertically movable plunger F and the head a rotatable on the lower end of the plunger, the mechanism best shown in Figs.

1, 5'and 6 of the drawings, which mechanism comprises a bell-crank o, pivoted at w to the front bar of the frame E and having oneof its arms adapted to move in a slot a:

of the frame bar, and its other arm adapted to move in the open portion Z of the plunger F, links y connecting the last named arm of the bell-crank and the open portion Z of plunger F, and disposed at opposite sides of the forward portion of the endwise movable bar D, a link 2 extending between and connecting the forward end of said bar D and the depending arm of the bell-crank 1), bellcranks a best shown in Fig. 2, fulcrumed in the bifurcated lugs 8 below the frame 1 and having depending arms pivoted to links 19 pivoted to and extending inwardly from I the grippers J, and links 0 pivoted to the 1 other arms of the bell-cranks and to deljpending lugs (Z on the head a, which latter is-adapted, as before stated, to rotate freely about the lower portion of the plunger F, and is also adapted to be raised and lowered by the said plunger. Thus, when it is deisired to move the grippers J inwardly to take hold of a brick, or outwardly to releasea brick, the supplemental handle 2' is released from the keeper portion 7' of the 1 main handle 6, and the operating connec- Ttion is from the said supplemental handle 2' through the rod 1), the link 2, the bell-crank 'v, the links g the plunger F, the head 92, the links 0 the bell-cranks a and the links b ,to the grippers J; it being manifest that ii on forward movement of the supplemental handle 71 and rod D, the grippers J will be opened, while when said handle 2' and rod D are retracted, the grippers J will be moved inwardly or toward the center about which 6 they are grouped. It will also be manifest that by putting the toothed edge of the supplemental handle 2' in engagement with the keeper portion f of the main handle 6,

the grippers J may be detachably secured "iin their inward positions and in that way.

retained in engagement. with a brick, so l revoluble frame carried by the first-named cameos as to enable the workman while manipw lating the body A with one hand to rotate tlie-grippers'about their center by manipulating the supplemental handle 9 with his other hand; Then when the gripped brick is in the position desired and it is in order to release and deposit the same, the workman has but to-disengage the supplemental handle 2' from the keeper portion 7 and move the said handle 11 and the rod D forwardly, when the grippers will be positively swung such changes in the form, construction and relative arrangement of parts may be'made as do not involve departure from the scope of my invention as defined in the claims appended.
